RT Journal Article SR Electronic T1 Involvement of interleukin 6 in SARS-CoV-2 infection: siltuximab as a therapeutic option against COVID-19 JF European Journal of Hospital Pharmacy JO Eur J Hosp Pharm FD British Medical Journal Publishing Group SP ejhpharm-2020-002322 DO 10.1136/ejhpharm-2020-002322 A1 Tomás Palanques-Pastor A1 Eduardo López-Briz A1 José Luis Poveda Andrés YR 2020 UL http://ejhp.bmj.com/content/early/2020/06/04/ejhpharm-2020-002322.abstract AB The aim of the study was to explore the involvement of interleukin 6 in SARS-CoV-2 infection, and to position the drug siltuximab in the management of severe forms of COVID-19. A bibliographic search was performed in Pubmed on the immune response to the disease, and in ClinicalTrials.gov on clinical trials with interleukin 6 blockers. Interleukin 6 is involved in the cytokine cascade, which originates as a consequence of an excessive immune response secondary to viral infection, aggravating lung affectation. Blockers of this cytokine (tocilizumab, sarilumab and siltuximab) are being studied as a strategy for treating the disease. Siltuximab is a monoclonal antibody indicated in Castleman's disease that could be administered in a single dose of 11 mg/kg in severe forms of COVID-19 that have increased interleukin 6.
